GeoMesa Export Request Error

Question

Problem: When I try to execute the request below, it gives an error. Is there a flaw in the CQL query or is there no jar file? Also, is this just a GeoMesa error or a drive error. Is there any other way to query GeoMesa and get the results in a CSV file?

Namespace: myNamespace
Collection: d1temp

Inquiry:

geomesa export -u user -p password -c myNamespace.d1temp -f d1-json -q "WITHIN(geom, POLYGON((-6.4101 55.597244,-6.4101 50.947156,0.656067 50.947156,0.656067 55.597244,-6.4101 55.597244)))"

Error:

Answer 1

This error occurs with Java 7. GeoMesa requires Java 8. The java -version command will show you the details of the version of Java you are using.

, Java JAVA_HOME, Java 8. !
